Neil Finn says Fleetwood Mac role is long-term

But Buckingham joined Fleetwood, Stevie Nicks, Christine McVie and John McVie for a 2014 reunion tour and a MusicCares ceremony in NY in January.

Drummer and founding member Mick Fleetwood told CBS News both new members have a legacy of their own.

Kiwi musician Neil Finn says he had a big grin on his face when he was invited to join legendary band Fleetwood Mac, because it's a call "you never expect to get".

The British-American soft rock band announced plans this week to stop in Sacramento at 8 p.m November 23 concert as part of a 52-date, six-month tour beginning in October. "I can't wait to play some more", he said at the time.

"This was not a happy situation for us in terms of the logistics of a functioning band".

The "Chain" group have enlisted Crowded House's Neil Finn and Tom Petty and the Heartbreakers guitarist Mike Campbell to replace Lindsey on their upcoming tour and are looking forward to performing songs they haven't performed live in years. As a matter of fact, Finn was in his hometown of Auckland when he got the life-changing call. They don't need to have a calling card.

And neither Campbell nor Finn are thinking of this as a temporary gig.

"Not to hedge around, but we arrived at the impasse of hitting a brick wall". But it's like a marriage that came to an end and there are reasons why... Watch the band's full CBS News interview below.

"We sat around a table and we just started listening to everybody we could think of", Nicks said.

"The essence of the band was great, and fun, and the three voices sound really good together", singer and keyboardist Chrstine McVie said.
